Application flied ivra ei, 1930. Serial No. 453,475.

. This invention'relates to anattachment for any liability of flooding the pump platform with oil and without incurring any waste of oil..

' Another object of the invention is to pro-' vide, in combination with an oil well pipe, a novelvalve means for venting the pipe when the same iselevated, so that the oilmay-fiow out and not be carried upwith the pipe in the elevation thereof.

This invention also consists in certain other features of construction and in the combina-' tion and arrangeinentof the several parts, to be hereinafter fully described, illustrated in the accompanying drawings, and specifically pointedout in the appended claims, 7 it being understood of course that minor.

changes may be made so longas they fall within the scope oftheclaims.

In describing my invention in detail, ref-r 'tion and constituting a contiuuationof F igure 1; r

Figure 3 is a viewin side elevation illus- I Figure 6 is asiniilarview on the line 66 of Figure 1.

Figure 7 is a horizont rection indicated by the arrows. 1

In the drawings the numerals 1 "and 2 indicate respectively upper and lower sections of the. well tube and the lower and upper ends of these sections, respectively, are

al sectional view on the'line 77 ot Figure 2 lookingfin the dithreaded intoa cylindrical valve casing 3 which is formed at diametrically opposite points with vertically extending bores 4 which open at their upper ends through the upper sideof the said casing 3 and the casing is providedwith ports 5 located a short distance above the lower end oi each bore and communicating with the interior of the casing 3 at a point between the ends of the tubes 1 and 2. An annular head 6 is slidably fitted to the lower end of the tube 1 and normally held in a downward orlowered position through the medium of a compression spring 7 which is secured at its upper end to the tube 1 and bears at its lower end against. the upper side of the head 6. The head} is formed, in its outer periphery, with radial slots 8 which are located diametrically opposite each other and mounted in each of the bores 4 is a tubular valve 9, the bore of which is indicated by the numeral 10, and each of the valves is provided with a bore 11, and, above the bore 11 with spaced heads 12 and 13 and, the portion of each bore between the heads is seated in respective ones of the slots 8, theheads 12 and 18 engaging respectively,

the under and upper sidesof the head 6.

The under side of the head 12 of each valve is beveled as indicated by the numeral 14 to engage and seat upon abeveled'seat 15 formed at the upper end of the bore 4 and it will be evident at this point that when the valve head 6 and the tubular valves 9 are in the positions shown inFigurel, the valves will be closed or, more specifically, the valve 9 will close the port 5 and the wall of the bore 4 will close'the port 11. For a purpose which will be made apparent, stems 16, four in number, are arranged in equidistantly spaced relation, for sliding movement in bores 17 formed in the casing 3 and the said stems 16 are symmetricallvarranged with respectto; the valves. 9 as will beevident by reference to Figure 4. The upper ends of the stems are threaded, as indicated by the numeral 18, into threaded openings formed in the head 6 and thelower ends of the stems project below the lower end of the valve casing 8.

Mounted upon the well tube section 2 for I rotative movement, is a swage 19; This swage lower ends of the stems 16.

end of upwardly beveled heads 9A- the inner side faces of which are inclined as indicated by the numeral 25 to correspond to the taper of the swage 19 and the outer sides of which i are substantially plane and vertically disposed and which are formed witha series of teeth A barrel 27, of cylindrical form ismounted upon the tube section 2 below the cylindrical extension 5200f the swage 9. The lower ends of the stems 23 are turned outwardly at right angles as indicated by the numeral 28 and 7 project through vertical slots Qilformed in the said barrel 27 and in, the normal positions assumed by the parts as shown in Figure 1, and

these outwardly turned ends 28 engage at the upper ends of the slots 29. The tube section 2 is formed with an outstanding rib 30 and the bore of the barrel 27 is formed with longitudinal grooves 31 in which the lugs 30 may slidably engage in the upward movement of the section 2 of the well tube. At its lower end the barrel 27 is interiorly increased in diameter as indicated by the numeral and a compression spring 33 is arranged upon the tube section Qand engages at its upper end in the enlargement 32 and bears against the annular shoulder 34 which is provided by the formation of this enlargement. A collar 35 is slidably mounted'upon the tube section 2 and is engaged by the lower end of the spring 33 and a similar collar 36 is fitted to the tube section 2 below the collar 35 and a stud 37 upon the tube section 2 is engageable in a bayonet slot 38 formed in the lower edge of the collar 36. Outwardly bowed leaf r springs 39 are secured at their upper ends in any appropriate manner to the collar and preferably these springs are three in number andare equidistantly spaced about the cir cumference of the two collars to which their ends are secured. 7

At this point it will be understood that the collar 36 is restrained against downward movement upon the tube section 2 and therefore, when an upward pull is exerted upon the tube section 1 and incidentally the tube section 2, the upward movement of the collar 36 will cause an expansion of the leaf springs 39 as the upward movement of the collar 35 is restrained by the compression spring 33. At the same time, the spring 33 is placed undercompression and therefore the swage 19 will be moved upwardly and likewise the heads 24 will be shifted radially outwardly as their inner sides ride upwardly over the upwardly inclined surface of the said swage and, finally, the teeth upon the outer faces of the heads 24 will engage the well lining and at this time the upper end of the swage will have engaged the lower ends of the stems 16 thus causin an upward displacement of the valve head -6 and upward displacement of the tubular valves 9 thus uncovering the vale seat 15 and exposing the ports 5 and 15.
